Forget his cheeky-chappy charm, his flowing hair and his rugged yet dashing look.

One Direction heartthrob Harry Styles claims the best thing about dating him is, in fact, his FOUR nipples.

In an extended interview with his DJ pal Nick Grimshaw, which airs on Friday morning, the former 1D star revealed some of his best and worst dating habits and even admitted he hadn't been on a date for while.

He confessed to being a snorer and described his four nipples as being his best trait.

The 23-year-old singer said: "I think I snore and also I quite like routine, so I don't know if I'm incredibly spontaneous. Best trait ... I don't know, it's weird to pick your best. Shall we go with the nipples thing."

Hunky Harry, who has a reputation for being something of a ladies' man after dating the likes of Caroline Flack, Taylor Swift and Kendall Jenner, also disclosed he'd prefer to be gunged in green slime than face any of his famous exes.

During the candid interview DJ Nick joked: "Did you think we'd do something weird like bring all your exes in?"

Harry also revealed he hadn't dated anyone in "a long time" after being busy filming war movie Dunkirk alongside working on his first solo material.

Harry said: "I haven't dated in a long time really because I went away to do the movie then did the album so I haven't in a while. I have a couple of candles left still, though."

Asked if it's hard to date as a celebrity, Harry explained: "I don't know, maybe. I feel like with all of the stuff how people date now with all online stuff I feel like you can do that (Google) with anyone really. If you're looking at someone's profile before seeing them it's kinda the same...

"I used to (research dates), then I said I'm not going to do that anymore, it's impossible to go in without a perception of someone and you've never met them and I started feeling like that was wrong and weird."

The much-anticipated premiere of Harry's debut single will be at 8am tomorrow on the Radio 1 Breakfast Show.
